The degree of difficulty of JEE MAIN varies every year. A great score one year may not be necessarily a great score next year. Some years paper is very easy and everyone gets high scores so the cutoff required also becomes high. The opposite is also true.
So what you can do is keep your focus on All India Ranks of JEE Mains and go through to the cutoffs as admission is based on that.
Here are the cutoff trends for Mechanical Engineering at NIT Surathkal in recent years.
